With a speed of 88.738 km/h (55.077 mph), the University of New South Wales’ Sunswift IVy has claimed the Guinness World Record for the fastest solar-powered vehicle. The record-beating run took place on January 7 at HMAS Albatross navy base airstrip in Nowra, Australia, and outdid the previous record-holder by more than 10 km/h (6.2 mph).
